Release 1.9.0

• Fixed bugs:

  • Fixed issue identified by Google fuzz where a CBOR classical multi-dimensional array
    contained elements of typed array.

  • Git PR #727: fix CBOR parser issues the fuzzer exposed

• Changes

  • The type name string_source has been deprecated and renamed to chars_source.

  • The class binary_iterator_source has been removed (replaced by iterator_source).

  • The type name order_preserving_policy has been deprecated and renamed to
    ordered_policy. For backwards compatibility the old name is aliased to the new name but
    will be removed in a future release.

  • The type name json_conv_traits has been deprecated and renamed to json_traits.
    For backwards compatibility the old name is aliased to the new name but
    will be removed in a future release.

• Enhancements:

  • Until 1.9.0, cbor and msgpack cursors read key-value pairs
    and convert the key part into a string before making it
    avaliable to the cursor as a staj_events::key event .
    Since 1.9.0, cbor and msgpack cursors read key-value pairs
    and make both string and non-string keys available to the cursor
    as a value event ORed with a key flag (staj_events::key_flag).
    For backwards compatibility, staj_events::key is now defined as
    staj_events::string_value | staj_events::key_flag.

  • For the common case of CBOR or MessagePack unsigned integer keys,
    the enum value id has been added to sjaj_events,
    defined as staj_events::uint64_value | staj_events::key_flag.

    cbor::cbor_bytes_cursor cursor{data};
    while (!cursor.done())
    {
        switch (cursor.current().event_type())
        {
            case staj_events::id:
                auto id = cursor.current().get<uint64_t>();
                // handle unsigned integer key event
                break;
        }
    }

  • When decoding a CBOR or MessagePack array of maps that have unsigned
    integer keys, code like

  auto m = cbor::decode_cbor<std::vector<std::map<uint64_t, std::string>>>(data);

  produces the same result as 1.8.0, but no longer results in conversions
  from integer to string and back to integer.

  • Reduced allocations when parsing BSON, CBOR, MessagePack and UBJSON.

  • JSONCONS_ALL_MEMBER_TRAITS, JSONCONS_N_MEMBER_TRAITS,
    JSONCONS_ALL_MEMBER_NAME_TRAITS, and JSONCONS_N_MEMBER_NAME_TRAITS now
    generate decode traits that support decode without an intermediate
    basic_json value.
